According to molecular orbital theory, which of the following statement is not correct?
- A \(\mathrm{C}_2\) molecule is diamagnetic in nature
- B Bond order of \(\mathrm{C}_2\) molecule is 2
- C \(\mathrm{C}_2\) - ion is paramagnetic in nature
- D \(\mathrm{C}_2\) consists of \(1 \sigma\) and \(1 \pi\) bond
Answer & Solution
Correct Answer
(D) \(\mathrm{C}_2\) consists of \(1 \sigma\) and \(1 \pi\) bond
Step-by-step Solution
Detailed explanation
\(\mathrm{C}_2=12\) electrons \(\therefore(\sigma 1 \mathrm{~s})^2\left(\sigma^* 1 \mathrm{~s}\right)^2(\sigma 2 \mathrm{~s})^2\left(\sigma^* 2 \mathrm{~s}\right)^2\left(\pi 2 \mathrm{p}_{\mathrm{x}}\right)^2=\left(\pi 2 \mathrm{p}_{\mathrm{y}}\right)^2\) Bond order…
